Patent EP-0383638-A3 (EP)
Title: Laser oscillator/amplifier with compensation for stress birefringence
IPC: H01S3/23
Filed: 1990-02-19
Abstract: A laser oscillator/amplifier system in which 
thermally induced birefringence in the gain medium of 
the oscillator is compensated by thermally induced 
birefringence in the gain medium of the amplifier. The 
system produces a quality output beam efficiently and 
with high power density in the preferred polarization. 
The oscillator cavity (10) has a high 
reflector (12) at one end and an output coupler (13) at the 
second end with an oscillator gain medium (14) exhibiting 
thermally induced birefringence in between. An 
amplifier (11) exhibiting thermally induced birefringence 
which matches the thermally induced birefringence in 
the oscillator gain medium is mounted to receive the 
output of the oscillator cavity. A ninety degree 
rotator (21) is mounted between the oscillator gain medium (14) 
and the amplifier (11) so that thermally 
induced birefringence in the oscillator gain medium is 
compensated by the matching thermally induced 
birefringence in the amplifier. The ninety degree 
rotator may be mounted inside the oscillator cavity, 
that is, between the oscillator gain medium and the 
output coupler; or it may be mounted outside of the 
oscillator cavity, that is, between the output coupler 
and the amplifier, as shown.

Abstract: Acrylate polyesters are made by the reaction of a 
diol (in particular polyoxyethylene or 
polyoxytetramethylene glycol), a dibasic acid anhydride 
(e.g. succinic or phthalic anhydride) and glycidyl 
acrylate. The polyester can be formulated into radiation 
curable compositions, in particular by blending it with a 
polyethylenically unsaturated radiation-curable compound 
and, optionally, a monoethylenically unsaturated 
radiation-polymerizable monomer, which compositions can be 
used as coatings, inks, and adhesives which cure at high 
rates when exposed to actinic radiation.

Patent EP-0484858-A3 (EP)
Title: Balanced self adjustable escalator handrail drive
IPC: B66B23/04
Filed: 1991-11-04
Abstract: The handrail drive utilizes one or more pairs of drive rollers which form a nip through which the handrail moves. The drive rollers are mounted on rotating drive shafts which in turn are eccentrically mounted in rotatable bearings. The drive rollers will automatically tighten on the handrail as friction increases between the rollers and handrail due to increased resistance to movement of the handrail. The rotatable bearings are connected together to ensure that each roller tightens equally on each side of the handrail so that the handrail is not bent through an S curve as it passes through the drive roller nip. <IMAGE>

Abstract: The following constitution is employed for enhancing
the visual recognition of a road traffic sign by presenting a
road traffic sign composed of a solid pattern having shades
as visual image. A marking pattern divided into plural
sections is tightly formed on the road, and the adjacent
sections are mutually different in lightness, so that, in
the road traffic sign of the invention, a solid figure is
recognized as the visual image of the marking pattern.
Herein, the adjacent sections have a lightness difference of
1 or more in Munsell value, and the lightness of each section
is selected at lightness in two to four stages set at
mutually different Munsell values. Moreover, when the
adjacent sections are colored in hues mutually different in
lightness, a more solid visual image will be obtained due to
the difference in hue among the sections.
